I would REALLY like to have support for moisture sensors. If this worked I would put sensors around my home foundation. Here in Texas we have tons of problems with foundations getting cracked as the level of moisture around the home changes.

I envision surrounding my home with around 8 sensors and then controlling valves specific to different areas around the house.

There are no specific sensors I have in mind. I have found them from $50 to $150. Whatever HydroFlash decided to support I would use. And if you guys sold them (without a HUGE mark up) I would gladly buy them from your store.
